I tried the JB thing but didn't find enough benefit with it to keep jailbreaking after each update. Colleagues here have said the same thing as well. Good for Comex, maybe he'll do well at Apple.
I would assume since no hardware exploits have been found for the a5 that untethered jailbreaks will soon be fading away as older devices aree replaced with newer ones and without the untether its not nearly as much fun
It's a given that he will do that but there are more people out there able to create JB tools. Thankfully comex is the not ruler of the JB world. Brilliant as he may be someone else will must take his spot and in a few months it will be "comex who?"
